Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor equipment, and in particular relates to a material distributor buffer bed structure. Background Technology

[0002] In the material conveying process of industrial production, belt distributors are key equipment for material diversion and transfer. Their structural stability and operating efficiency directly affect the smoothness of the entire conveying system. Currently, conventional belt distributors mostly use a buffer roller structure at the bottom. Through the support and rotation of the rollers, in conjunction with the action of the distributor, the separation and transfer of materials are achieved.

[0003] However, in practical applications, the traditional buffer idler structure has significant drawbacks. Taking the belt distributor used in the ironmaking pellet conveyor as an example, the conveyor belt is 800mm wide, while the matching buffer idler frame is only 620mm wide. When the distributor is working, the bottom buffer idler rises and presses against the distributor to complete the distribution action. However, because the width of the idler frame is smaller than the belt width, the edges of the belt extend beyond the idler frame and press directly under the chute. This structural mismatch causes problems mainly in the following aspects:

[0004] During the material distribution process, materials are prone to leaking out from the gap between the two sides of the belt and the chute, resulting in material waste. At the same time, the leaked material accumulates around the equipment, increasing the amount of cleaning work.

[0005] When leaked material falls onto the return conveyor belt, it causes uneven stress on the belt, leading to belt misalignment. Belt misalignment not only affects material conveying efficiency but also increases friction between the belt and the equipment edges, shortens the belt's lifespan, and increases equipment maintenance frequency and costs.

[0006] Long-term material leakage and misalignment can also trigger a chain of failures, such as belt jamming and motor overload. In severe cases, it can even cause the entire conveyor system to shut down, affecting the continuity of production. Utility Model Content

[0007] This invention addresses the problem of material leakage from the gap between the belt and the chute during the traditional material distribution process. It provides a buffer bed structure for the material distributor, which reduces material leakage, prevents belt misalignment, and improves equipment operational stability.

[0008] The technical solution adopted by the present invention for a feeder buffer bed structure is as follows:

[0009] A feeder buffer bed structure includes a feeder body, and a buffer bed assembly replacing the traditional buffer roller is provided at the bottom of the feeder body. The buffer bed assembly includes a support frame, and a buffer panel adapted to the width of the conveyor belt is laid on the top of the support frame. At the same time, the support frame is fixedly connected to chute plates arranged on both sides of the buffer bed assembly. The chute plates can move synchronously with the support frame, and their width can cover the side of the conveyor belt.

[0010] A further improvement of this utility model is that the chute and the support frame are fixedly connected by welding, and the weld is a full weld structure with a weld thickness of not less than 5mm.

[0011] A further improvement of the present invention is that the bottom of the support frame is provided with a lifting mechanism that can drive the support frame to move up and down.

[0012] A further improvement of the present invention is that the lifting mechanism includes a hydraulic cylinder, the cylinder body of which is fixedly connected to the main body of the distributor, and the piston rod of which is fixedly connected to the support frame.

[0013] A further improvement of this utility model is that the chute is inclined downwards in a direction away from the buffer panel, with an inclination angle of 5°-10°.

[0014] A further improvement of this utility model is that the chute is provided with a wear-resistant liner made of high manganese steel on the side facing the conveyor belt.

[0015] A further improvement of this utility model is that the support frame is welded from channel steel, and the channel steel is a No. 10 channel steel.

[0016] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0017] This invention replaces the buffer idler roller with a buffer bed assembly and widens the chute to match the belt width, ensuring complete coverage of both sides of the belt. This eliminates material leakage caused by insufficient idler roller width in traditional structures, reducing material waste and cleaning costs. Simultaneously, with the leakage problem resolved, the amount of material falling onto the return belt is significantly reduced, preventing uneven stress on the return belt due to material accumulation. This fundamentally reduces belt misalignment, extends belt life, and lowers equipment maintenance frequency.

[0018] The material conveyor plate and the support frame of this utility model are connected by full welding, and the support frame is made of 10# channel steel, which ensures the overall structural strength of the buffer bed assembly, can withstand the vibration and compression during the material distribution process, and improves the operational stability of this utility model.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figure 1-2 As shown in the figure, the present embodiment discloses a feeder buffer bed structure, including a feeder body 1, a buffer bed assembly 2 and a conveyor plate 3.

[0023] The main body 1 of the above-mentioned distributor adopts the main structure of the existing conventional distributor and is used to realize the diversion control of materials. Its specific structure will not be described in detail here.

[0024] In this embodiment, the buffer bed assembly 2 is located at the bottom of the distributor body 1, replacing the traditional buffer roller. The buffer bed assembly 2 includes a support frame 21 and a buffer panel 22. The support frame 21 is welded from 10# channel steel, and has an overall rectangular frame structure. Its length is adapted to the bottom length of the distributor body 1 (approximately 1.2m), and its width is 850mm (slightly larger than the belt width of 800mm). The buffer panel 22 is made of ultra-high molecular weight polyethylene (UHMWPE) sheet with a thickness of 20mm. It is laid on top of the support frame 21 and fixedly connected to the support frame 21 by bolts. The width and length of the UHMWPE sheet are the same as the width and length of the support frame 21, and its surface is smooth, which can reduce friction with the belt.

[0025] In this embodiment, the chute 3 is disposed on both sides of the buffer bed assembly 2 and is made of steel plate with a thickness of 8mm. A high manganese steel wear-resistant liner 5 with a thickness of 5mm is welded to the side of the chute 3 facing the conveyor belt. The wear-resistant liner 5 is fixed to the chute 3 by rivets. The chute 3 is tilted at 7° away from the buffer panel 22 to guide a small amount of possible material leakage to slide to the outside of the equipment. The bottom of the chute 3 is connected to the side of the support frame 21 by full welding with a welding thickness of 6mm. After welding, the weld is ground to ensure that the connection is firm and burr-free.

[0026] In this embodiment, the lifting mechanism 4 is located at the bottom of the support frame 21 and includes two hydraulic cylinders of model HSG01-100 / 50. The two hydraulic cylinders are symmetrically distributed at both ends of the support frame 21 along its length. The cylinder body of the hydraulic cylinder is fixedly connected to the bottom of the distributor body 1 through a flange, and the piston rod end of the hydraulic cylinder is connected to the ear plate at the bottom of the support frame 21 through a pin. By controlling the extension and retraction of the hydraulic cylinder through the hydraulic station, the support frame 21 can be driven to move up and down, thereby driving the chute 3 to move synchronously, so as to achieve pressing or separation from the distributor body 1.

[0027] The working principle of the feeder buffer bed structure in this embodiment is as follows: When the feeder starts working, the hydraulic station is activated, controlling the piston rod of the hydraulic cylinder to extend, pushing the support frame 21 to move upward, driving the buffer panel 22 and the chute 3 to move upward synchronously until the buffer panel 22 contacts the conveyor belt and the chute 3 is pressed against the side of the feeder body 1; at this time, the pellet material conveyed by the conveyor belt is diverted under the action of the feeder; since the chute 3 is pressed against the feeder body 1 along with the support frame 21, the material cannot leak out from both sides of the belt; the ultra-high molecular weight polyethylene material of the buffer panel 22 reduces friction with the belt, and the high manganese steel wear-resistant liner 5 reduces wear between the belt and the chute 3; when the feeding is finished, the piston rod of the hydraulic cylinder retracts, driving the support frame 21, buffer panel 22 and chute 3 to move downward, separating from the feeder body 1, waiting for the next feeding.

[0028] In the above embodiments, this utility model provides a feeder buffer bed structure. By replacing the buffer rollers with a buffer bed assembly and widening the chute to match the belt width, the edges of the belt are completely covered, eliminating material leakage caused by insufficient roller frame width in traditional structures, reducing material waste and lowering cleaning costs. Simultaneously, with the leakage problem solved, the amount of material falling onto the return belt is significantly reduced, avoiding uneven stress on the return belt due to material accumulation, fundamentally reducing belt misalignment, extending belt life, and lowering equipment maintenance frequency. The chute and support frame are fully welded together, and the support frame is made of 10# channel steel, ensuring the overall structural strength of the buffer bed assembly, capable of withstanding vibration and compression during the feeding process, and improving the operational stability of this utility model.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
